Stabilized body care products, household products, textiles and fabrics

ABSTRACT

Disclosed are stabilized body care products, household products, textiles and fabrics which comprise certain hindered nitroxyl, hydroxylamine and hydroxylamine salt compounds. Dyed products and articles are effectively stabilized against color degradation. The products are for example skin-care products, hair-care products, dentifrices, cosmetics, laundry detergents and fabric softeners, non-detergent based fabric care products, household cleaners and textile-care products.

The present invention relates to the use of selected hindered nitroxyl,hydroxylamine and hydroxylamine salt compounds for the protection ofbody care products, household products, textiles and fabrics against thedeleterious effects of light, heat and oxygen.

The stabilized compositions for example comprise dyes that arestabilized against color change.

-   inorganic pigments, for example iron oxide (Iron Oxide Red, Iron    Oxide Yellow, Iron Oxide Black, etc.), Ultramarines, Chromium Oxide    Green or Carbon Black;-   natural or synthetic organic pigments;-   disperse dyes which may be solubilized in solvents like direct hair    dyes of the HC type, for example HC Red No. 3, HC Blue No. 2 and all    other hair dyes listed in International Cosmetic Ingredient    Dictionary and Handbook, 7^(th) edition 1997) or the dispersion dyes    listed in Color Index International or Society of Dyers and    Colourists;-   color varnishes (insoluble salts of soluble dyes, like many Ca-, Ba-    or Al-salts of anionic dyes);-   soluble anionic or cationic dyes, like acid dyes (anionic), basic    dyes (cationic), direct dyes, reactive dyes or solvent dyes.

Generally, for the coloration of household- and body care products allsubstances are suitable which have an absorption in the visible light ofelectromagnetic radiation (wavelength of ca. 4000 to 700 nm). Theabsorption is often caused by the following chromophores: Azo- (mono-,di, tris-, or poly-)stilbene-, carotenoide-, diarylmethan-,triarylmethan-, xanthen-, acridin-, quinoline, methin- (alsopolymethin-), thiazol-, indamin-, indophenol-, azin-, oxazin-, thiazin-,anthraquinone-, indigoid-, phtalocyanine- and further synthetic, naturaland/or inorganic chromophores.

The present stabilizer systems are also used in household cleaning andtreatment agents, for example in laundry products and fabric softeners,liquid cleansing and scouring agents, glass detergents, neutral cleaners(all-purpose cleaners), acid household cleaners (bath), bathroomcleaners, for instance in washing, rinsing and dishwashing agents,kitchen and oven cleaners, clear rinsing agents, dishwasher detergents,shoe polishes, polishing waxes, floor detergents and polishes, metal,glass and ceramic cleaners, textile-care products, rug cleaners andcarpet shampoos, agents for removing rust, color and stains (stainremover salt), furniture and multipurpose polishes and leather and vinyldressing agents (leather and vinyl sprays) and air fresheners.

The present invention also concerns home care and fabric care productssuch as drain cleaners, disinfectant solutions, upholstery cleaners,automotive care products (e.g., to clean and/or polish and protectpaint, tires, chrome, vinyl, leather, fabric, rubber, plastic andfabric), degreasers, polishes (glass, wood, leather, plastic, marble,granite, and tile, etc.), and metal polishes and cleaners. Antioxidantsare suitable to protect fragrances in above products as well as in dryersheets. The present invention also relates to home care products such ascandles, gel candles, air fresheners and fragrance oils (for the home).

The stabilizers of the present invention may be employed in fabrictreatment that takes place after use of the fabric, referred to asfabric care. Such treatments include laundering, which uses detergentsand/or fabric conditioner, and the application of non-detergent basedfabric care products, such as spray-on products. When employed in thisfashion, the present stabilizers are intended for deposition onto thefabric and used to protect the fabric, colorants and fragrancesassociated with said these fabrics from environmental damage.

Typical examples of household cleaning and treating agents are:

Household cleaners/household treating agents Ingredients detergentconcentrate surfactant mixture, ethanol, antioxidant, water, uvabsorbers, antioxidant shoe polish wax, wax emulsifier, antioxidant,water, preservative, uv absorbers, antioxidant wax-containing flooremulsifier, wax, sodium chloride, antioxidant, water, cleaning agentpreservative, uv absorbers, antioxidant

The present stabilizers are for example incorporated by dissolution inan oil phase or alcoholic or water phase, where required at elevatedtemperature.

The present invention also pertains to a method of stabilizing a bodycare product, household product, textile or fabric, which comprisesincorporating therein or applying thereto at least one compound of theformulae (I), (II) and (III), for example at least one compound of theformulae A to EE and A* to EE*.

In the case of stabilized fabrics, for example dyed fabrics, the presentstabilizers are applied thereto via deposition from for instancedetergents, fabric conditioners or non-detergent based fabric careproducts.

The present fabrics are natural or synthetic, and may be woven ornonwoven.

The present invention also pertains to a method of stabilizing a bodycare product, household product, textile or fabric, each of whichcontain a dye, which comprises incorporating therein or applying theretoat least one compound of the formulae (I), (II) and (III), for exampleat least one compound of the formulae A to EE and A* to EE*. Thestabilizers of formulae (I), (II) and (III) are very effective towardsthe stabilization of dyes in the present compositions.

The textiles of this invention are for example textile fiber materials,for example nitrogen-containing or hydroxy-group-containing fibermaterials, for instance textile fiber materials selected from cellulose,silk, wool, synthetic polyamides, leather and polyurethanes. Includedare cotton, linen and hemp, pulp and regenerated cellulose. Includedalso are cellulosic blends, for example mixtures of cotton and polyamideor cotton/polyester blends.

The additives of the present invention are for example applied totextiles in a dyeing or printing process, or in a finishing process. Forinstance, the additives may be applied as part of a dye formulation. Theadditives may be applied to textiles for example h an ink-jet printingprocess. The additives are for example applied as part of an aqueous dyesolution or printing paste. They may be applied in an exhaust method ordyeing by the padder dyeing method, in which the textiles areimpregnated with aqueous dye solutions, which may contain salts, and thedyes and additives are fixed, after an alkali treatment or in thepresence of alkali, if appropriate with the action of heat or by storageat room temperature for several hours. After fixing, the dyeings orprints are rinsed thoroughly with cold and hot water, if appropriatewith the addition of an agent which has a dispersing action and promotesdiffusion of the non-fixed portions.

The dye or ink formulations for application to textiles may comprisefurther customary additives, for example surfactants, antifoams,antimicrobials and the like, for example as disclosed in U.S. Pat. Nos.6,281,339, 6,353,094 and 6,323,327, the disclosures of which are herebyincorporated by reference.
